File Modification

Changes made to a file, including updates to its contents, metadata, access permissions, or attributes. These modifications may indicate legitimate activity (e.g., software updates) or unauthorized changes (e.g., tampering, ransomware, or adversarial modifications). Examples:

• Content Modifications: Changes to the content of a configuration file, such as modifying /etc/ssh/sshd_config on Linux or C:\Windows\System32\drivers\etc\hosts on Windows.
• Permission Changes: Altering file permissions to allow broader access, such as changing a file from 644 to 777 on Linux or modifying NTFS permissions on Windows.
• Attribute Modifications: Changing a file's attributes to hidden, read-only, or system on Windows.
• Timestamp Manipulation: Adjusting a file's creation or modification timestamp using tools like touch in Linux or timestomping tools on Windows.
• Software or System File Changes: Modifying system files such as boot.ini, kernel modules, or application binaries.
